Introduction A composite material is defined as a combination of materials which has one or more different elements, which when combined together produce a material which is strong, stiff, tough and more durable than each individual element.
During the last decades, the application of composite materials has become increasingly popular especially in aerospace structures.
These materials can be of great benefit to aviation, as lighter materials translate into lower fuel consumption and higher performance of aircraft.

Simulation and proper experiments reveal that the dynamic performance of PMA can be improved through filling the PMA with materials of high thermal conductivity.
Then improvements of dynamic performance by filling the PMA with materials of high thermal conductivity are proposed.
Dynamic Performance Improvement Through filling PMA with materials of high thermal conductivity, the thermodynamic process can be changed from polytropic process to approximate isothermal process.
